  "message": "[PATCH] r/o bind mounts: elevate write count for open()s\n\nThis is the first really tricky patch in the series.  It elevates the writer\ncount on a mount each time a non-special file is opened for write.\n\nWe used to do this in may_open(), but Miklos pointed out that __dentry_open()\nis used as well to create filps.  This will cover even those cases, while a\ncall in may_open() would not have.\n\nThere is also an elevated count around the vfs_create() call in open_namei().\nSee the comments for more details, but we need this to fix a \u0027create, remount,\nfail r/w open()\u0027 race.\n\nSome filesystems forego the use of normal vfs calls to create\nstruct files.   Make sure that these users elevate the mnt\nwriter count because they will get __fput(), and we need\nto make sure they\u0027re balanced.\n\nAcked-by: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n",
